Possibly my favorite feature introduced in WordPress 2.6 was the wiki-style document revisions. You can now easily get access and/or restore old revisions. It took a few days to get used to, but I have to say I really love it!

I’ve always felt that this feature was intended primarily for multi-author blogs and probably isn’t needed for most WordPress bloggers, as it only serves to grow your wp_posts database table. If you are someone that would like to disable this feature, all you need to do is open your wp-config.php file and add the following code:

define('WP_POST_REVISIONS', false);

This should restore WordPress to handling posts the way it did in the WordPress 2.5 branch and earlier!
